Ethyl Acetate in Coatings and Printing Inks
Ethyl acetate (CAS 141-78-6) is a fast-evaporating ester solvent widely used in solvent-borne coatings, gravure and flexographic printing inks, and adhesive formulations. It offers a balanced evaporation rate, low viscosity and strong solvency for nitrocellulose, acrylic and vinyl resins, which is why it remains a top-volume solvent in paint and ink production.
Key Quality Parameters for Coatings Grade
| Parameter | Typical Coatings Grade |
|---|---|
| Purity | ≥99.9% |
| Water | ≤0.1% |
| Acidity (as acetic acid) | ≤0.005% |
| Evaporation rate (n-BuAc = 1) | ~2.8–3.0 |
| Color (APHA) | ≤10 |
Main Application Areas
- Coatings: Automotive basecoats, wood coatings, industrial paints as a co-solvent with ketones and aromatics.
- Printing inks: Fast-drying solvent for gravure and flexo inks on plastic films and packaging.
- Adhesives: Carrier solvent in rubber- and resin-based adhesive systems.
- Extraction and pharma: Solvent for flavours, fragrances and pharmaceutical intermediate purification.
